ABSTRACT

A new and distinct cultivar of  Hydrangea macrophylla  (Thunb.) plant named ‘BCHY-14.020’ originated as a controlled cross between varieties. The variety ‘BCHY-14.020’ has attractive inflorescences with sepalous florets with attractive sepal pigmentation and good commercial characteristics.

Botanical classification: Hydrangea macrophylla (Thunb.) ‘BCHY-14.020’.

Variety denomination: ‘BCHY-14.020’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct cultivar of the Saxifragaceae family. The botanical name of the plant is Hydrangea macrophylla (Thunb.) ‘BCHY-14.020’.

The new cultivar originated as a seedling from a controlled cross between a variety known to the inventor as ‘.BC6.8’ which was the seed parent and the commercial variety known as ‘Oslo’ which was the pollen parent. ‘BC6.8’ was the subject of U.S. patent application Ser. No. 13/135,035 which became U.S. Plant Pat. No. 24,144. ‘BC6.8’ originated as a seedling from a controlled cross between the unpatented variety known as ‘LK49’ which was the seed parent and a commercial variety known as ‘Venedig’ to the inventor which may be the subject of U.S. Plant Pat. No. 10,928 and registered as ‘Venice Raven’. ‘Venedig’ was the pollen parent of that cross. ‘LK49’ is relatively compact plant with wiry stems, relatively small leaves, relatively small sepalous florets, and inflorescences that are resistant to being damaged by conditions in commercial coolers. The applicant is unaware as to whether the commercial variety known as ‘Oslo’ is the subject of a patent in the United States or a foreign country or protected as a plant variety in the United States or a foreign country. No observations of the parent ‘Oslo’ were made.

The variety ‘BCHY-14.020’ has sepalous florets with somewhat variegated sepal pigmentation at maturity and good commercial characteristics, including strong stems, a propensity to branch when pinched and a propensity to set infloresences on each stem and lateral branch. The color of the sepals changes as the plant ages. The plant is similar to U.S. Plant Pat. No. 23,757 entitled Hydangrea Plant named ‘BC6.1’. Below is a table comparing the new variety to similar varieties.

The new cultivar ‘BCHY-14.020’ has been successfully asexually reproduced under controlled environmental conditions at a nursery in Half Moon Bay, Calif. under the direction of the inventor with its distinguishing characteristics remaining stable.

Asexual reproduction was first accomplished when vegetative cuttings were used from the initially selected plant. Examination of asexually reproduced, successive generations grown in Half Moon Bay, Calif. show that the combination of characteristics as herein disclosed for ‘BCHY-14.020’ remains firmly fixed.

DESCRIPTION OF THE NEW PLANT

The plants described are approximately a year old. The plant started out as cuttings, used from the stem of a grown plant. The plants shown were pinched early in their development to promote lateral branches. All of the plants pictured had soil that was periodically treated with aluminum. The plant shown in FIG. 6 was grown in a different cycle than the plants shown in FIGS. 1-5. All measurements and color determinations provided are based on the plant shown in FIGS. 1-5.

‘BCHY-14.020’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment. Color determinations were made with The Royal Horticultural Society (R.H.S.) Colour Chart, developed in association with the Flower Council of Holland, located in Lieden.

THE PLANT

-   Origin: Controlled cross. The new cultivar originated as a seedling     from a controlled cross between the patented variety ‘BC6.8’—U.S.     Plant Pat. No. 24,144—which was the seed parent, and the commercial     variety ‘Oslo’ which was the pollen parent. -   Form: Upright, non-climbing, compact shrub. The mature plant with a     mature inflorescence that is ready for sale is approximately 13″     high and has a diameter of 15″ when grown in a 6″ pot with     appropriate soil amendments. -   Growth: Upright, vigorous growth habit. Inflorescence is medium to     large. The plant branches easily with shoots forming at the base of     the plant. Lateral branches are similar in appearance and form to     the main stems. -   Stems: Lenticels are present. Stem lengths are approximately 9″.     Fasciation is absent. Lenticels are R.H.S. 86 A (violet group) and     are 1 to 3 mm long. The surface of young stems is glabrous. Stems     become woody as they age. The color of typical young stems and young     lateral branches is R.H.S. 144 A (yellow-green group). The older     portions of the stems are R.H.S. 199 A (grey-brown group). Younger     portions of the stems are 7 mm in diameter. Older portions of the     stems are 7 mm in diameter. -   Foliage: Abundant. Leaves are opposite on stem and lateral branches.     -   -   Shape of leaf.—Elliptic with acute base and acute apex. Tips             of leaves are 10 mm long. Margins are serrate and not lobed.         -   Texture.—Glabrous; veins dominate on the underside of the             leaf and are sunken on the upper leaf surface. The upper             side of the leaf is moderately glossy. Variegation is             absent.         -   Color.—Mature leaves have an upper side that is R.H.S. 136 A             (green group), and an under side that is R.H.S. 137 C (green             group). Leaves are pinnately veined. The midvein and veins             branching off the midvein are large and prominent on the             underside of the leaves. Veins are R.H.S. 145 C             (yellow-green group). Leaves are as wide as 10.0 cm and 15             cm long. Petioles are smooth and approximately 2.5 cm long             and 4 mm wide. Petioles are R.H.S. 145 C (yellow-green             group).

BUDS

-   Form: Globose with 4 to 5 connate, elliptic, smooth petals. The     terminal and later-developing buds of the panicles are non-sepalous.     The majority of buds will develop into sepalous florets. The buds     are approximately 2 mm by 2 mm when very young. Buds can be 5 mm in     diameter and still unopened. Color of mature buds is R.H.S. 96 A     (violet-blue group). -   Aspect: Smooth. -   Arrangement: Borne on branched panicles.

INFLORESCENCE

-   Form: Paniculate. Terminal. As many as 70 individual florets (both     sepalous and non-sepalous) per inflorescence. Both sepalous florets     and non-sepalous florets are borne on the same panicle. Non-sepalous     florets are inconspicuous. Flowers do not produce a fragrance. The     peduncle for the inflorescence is strong and upright. There are very     few non-sepalous florets. The non-sepalous florets are located at     the terminal portion of the panicle and are later hidden by sepalous     florets. Florets, both sepalous and non-sepalous, have anthers and     style. Inflorescences are long-lasting. Florets near terminal floret     have less developed sepals and are less pigmented. -   Size of inflorescence: Medium. Individual inflorescence size is     dependent on the number of florets. A typical inflorescence can grow     as large as 8″ in diameter, and 4″ high. -   Shape: Globose. Clusters of numerous small florets; sepalous florets     overlap one another. Sepals are persistent. -   Appearance: Showy.

FLORETS

-   General: The non-sepalous florets at the center of the panicles open     first. Sepalous and non-sepalous florets are perfect and complete.     Corolla: Generally, for both sepalous and non-sepalous florets there     are 4 petals. Petals are typically 4 mm long and 3 mm wide. Petals     are R.H.S. 97 A (violet-blue group). Lenticels are present on     pedicels of both sepalous and non-sepalous florets, lenticels and     range in length from 1 mm to 3 mm. Lenticels are R.H.S. 80 A     (purple-violet group). Pedicel length for non-sepalous florets     averages 3 mm. Pedicel length of sepalous florets is approximately     40 mm in length for plants of this age. Pedicels of both sepalous     and non-sepalous florets continue to elongate as the inflorescence     ages. In the observed plants, pedicels range from 96 B     (violet-purple group) at the base of the pedicel to R.H.S. 145 B     (yellow-green group) near the floret when mature. -   Stamens: 8 to 12 stamens. Anther is regular and basally attached.     The stamens are 5 mm long and are R.H.S. 96 A (violet-purple group).     The anthers are 2 mm long and are R.H.S. 145 A (yellow-green group).     Pollen is scarce. -   Stigma: Typically three style each with two to four style also being     common. Each style has one stigma. -   Ovary: Ovary is partially inferior. -   Sepalous florets:     -   -   General.—Veins dominate on the underside of the sepals.         -   Number of sepals.—4 to 5 sepals per floret.         -   Aspect of sepals.—Smooth and glaucescent.         -   Shape of sepals.—Reniform with acuminate apex. Edges are             entire, but with some crenation.         -   Size of sepals.—As the florets mature, the sepals enlarge             and overlap each other more and more, until, often, there is             no space between the sepals when the petals of the florets             open. Sepals at maturity are typically 40 mm long and 50 mm             wide. Sepalous florets can be 70 mm in diameter. In the             observed plants, the upper sides of the sepals are             variegated in color with the centers being R.H.S. 96 C             (violet-blue group) and the margins being R.H.S. 83 B             (violet group). In the observed plants, the undersides are             R.H.S. 88 B (violet group). Pigmentation develops at the             tips of the sepals and travels inward towards base of the             sepals. -   Fruit: None. -   Disease and pest resistance: Unknown. -   Plants prefer milder temperatures. -   Plants bloom in the spring but can be forced to bloom by placing in     a cold environment.
